I am running out of ideas on how to make a mechanical fuel pump keep two Holley 600's full at WOT.
I refuse to convert back to a electric pump full time but a helper pump might take care of the issue. I read the thread from June 16 about running an elctric through a mecahnical.
Is there a particular brand that lends itself to this setup? I see Carter has a4600 seies rated at 8 PSI and a 4601 rated at 15 PSI. Would the 15 be too much pressure on a mechanical?

I would only want to use the electric 1% of the time
